ROTARY EXELUSIUN ETGTOE.

To all whom it may concern Be it known that l, Fimosmc BECK, s subgeot ot the Emperor of Germany, residing a -16 Rue Yhry, hleuilly-sur-Seiiie, filei-zoe,

Frsnce, have invented a certein'new sod useful Rotary Exolosion-Motor, of which the following is aspecification.

a rotary motor in which the pistons are displaced in ring-like elements which receive a continued circularinotion around a fixed crankshaft passing through the center or the ring to which the elements considered; are attached. j

The object which it is desired to ohtaini is to produce a motor which shall be easily cooled and which shall have a high power.

The arrangements shown hereinafter allow of eiiecting this double result.

011 the accompanying drawing 1s. diagrsmmaticelly represented a method of construction of the motor which is the object oi? the invention.

Figure l. is e section on the line l- -i oi Fig". Fig. 2 is e section along the line 11-41 of Fig. 1. Fig. 3 is a plan view in detail oi the device for controlling the valves. Fig. 4: e diagrammatic view of the cam mechsnism which operates the valves.

As is seen from the figures the arrange ment of the motor is as tollowSz-The twin ring elements 1, 2; 1 2 which constitute the working cylinders of the motor ere fixedly connected by s suitable arrangement, to the two plates 3,3 through the center of these plates passes crenl-r-shaft e.- tirovided with two creek-pics to which shaft they serve as supports and on which they can rotate, this shaft lalways remaining fixed end invariable in position. U11 each crank-pin is mounted a crank 5, (5 the end of which is cohnectedto a right-angled bell-oranlr lever 6, (6 which is common to the pistons of a group of ring-elements 1, L (or 2, 2 this hell-crank lever which can oscillate around an axis 7, ('i" serving as a tie be tween the plates 3, 8, is pivoted at its other end to a swing her 8, (8",) by means of s small crank '9, (9 This swing hair 'o'ocrates the ro i0, ll (1& 11 of each of the mounted on iivoted to the Specification of Letters Patent.

from the centrifugal force which tends to push them agtiinst the internal face of the exterior wall of the rim element, which mpidly causes the ring-e emeiitto become oval in section.

At, the end of each working cylinder Q provided a chamber so situated that it lies The present invhntion has for its object -.ielemeut; at each end of this chamber is provelve 17, serves for sdalone" a radius of the section of the ringvided e. velve; the mission and the valve 18 for exhaust. 'lhis chamber is common to the twin ring-elements. V

As shown in the drawings, the admission valve is placed on the radius nearer the center than the exhaust valve, which is placed at the extremity of the radius. This arrangement has for its object to'equalize the centrifugal force, either at the admission of the fresh gas or t the exhaust of the burned gases. These valves are operated in the following manner: In the plates 3 is mounted a cam shaft 19 for each grou of tour neighboring valve chambers. This shaft carries a toothed pinion 20 which with a pinion 21 fixed connected with a wheel 22 loosely mounted on so provided in the plates 3. This toothed wheel gears with a pinion 23 fixedly mounted on the shaft 4;. If the wheels, 23 22 and 20, are given the same diameter and the pinion 21 half this diameter, it will be seen that on the rotation of the whole mechahisin' together with the plates 3, the cam shaft will. turn with half the speed ot the rest of the mechanism. tions, it on an onderhung shaft 24 mounted in the plates 3, and parallel to the shaft 19, a righteiigled hellcrank lever 25, 26 is provided it will be possible with the same cam to control the admission and. exhaust valves of one of the chambers. By providmg on an axis 24:, symmetrical with the first axis 24: as re 'ards a radius passing through the axis of the shaft 19, a right angled bellcrank lever 25 26 arranged similarly to the ri 'ht-angled bell-cranlt lever 25,26 it will he possible with another cam provided on. the same shaft 19 to control the exhaust end admission valves of the other chamber. This particular method of control i partially represented in plan in Fig. 2e hell-circuit lever 25, 26 pivots nod-er the action oi? the cam 27 around the axis 34=; when the cam. operates the roller of the srin the arm 26 is lifted and Under these condi-,

operates the rod 29 attached to the member 30; the exhaust valve then opens; when the cam operates the roller 31 of the arm 26, this arm moves toward the chamber and opens the admission valve by acting on the member 32. The cam 27 arranged at 180 with regard to the cam 27 acts in the same manner on. the bell crank lever 25 26 The working or". this motor is as follows :-I.t', in the'case 'of'Fig. 1 the cylinders A are supposed to be in the explosion period, the cylinders B will be in the compression position and the ring elements and the motor together with the pistons 12, 14:;

13, 15 will turn around the fixed crank-shaft in the direction of the arrow At the same time the cylinders A are in the exhaust position, and the cylinders B are in the suction position. The cycle is then developed in each working cylinder, at the rateof four explosions. or two double explosions per revolution.

It will be remarked that in this motor the absolute movement of the pistons is not alternative, the phases of the cycle being effected by the greater or less speed of the ring elements with regard to the pistons, which remain stationary during the exhaust periods. On the other hand, the general arrangement: allows of providing large ports in those parts of the ring elements in which the pistons do not engage, or even of suppressing them together. This is a simple method of lightening the motor, and

at the same time assures cooling.

It is evidently possible by mounting them on the same shaft to group together a series of motors thus constituted of ring elements, either twin or not, with the members which have been described; the separate motors may be fixedly provided with regard to a varied circular motion to the.

each other, so as to assure in the: most convenient manner, the balancing of the rotating parts, and the-regular repetition of the explosions in each revolution; in this manner the power of the motive group may be increased at will with the least amount of encumbrance.

What I claim asmy invention and desire to secure by Letters Patent is '1. In a rotary explosion motor the combination of twin ring-elements constituting the working cylinders, pistons provided in the ring elements, means for transmitting pistons, valve chambers common to the twin-ring elements, admission and exhaust valves contained in the said valve chambers, and means for simultaneously operating the admission and exhaust valves, of a pair of twin ring-elements.

2. In a rotary explosion motor the combination of twin ring-elements constituting the working cylinders, pistons provided in the ring elements, means for transmitting a varied circular motion to the istons, valve chambers 1 common to the twin ringelements, admission and exhaust valves contained in the said valve chambers, and means for simultaneously operating the admission and exhaust valves, of a pair of twin ring-elements, and means for preventing the elfect'of centrifugal force on the section of the respective ring-elements.

In testimony whereof I have'hereunto signed my name to this specification in the presence of two subscribing witnesses.
